Say u see something for sale, but u only have $200 in your savings account, but the item costs $500. You borrow that from the bank (credit), then pay it back, say after u get ur paycheck for the week/fortnight etc before interest kicks in.
UTS, move ur math1141 tut on tuesday to 4-5pm instead of 5-6 :), might as well make it 5 hours straight :), or u wanna have a break then do the 1141 tut?
